Third in a darkly enchanting trilogy after Begone the Raggedy Witches and The Little Grey Girl, The Promise Witch opens in a time of heat and thirst. The deposed old tyrant of a queen sent a cursed winter to bury Witches Borough in snow. Months later, the clouds have vanished, but an equally cursed drought has settled over the castle and its river, now bone-dry. Witches Borough is dying, and though Mup is the pathfinder, the stitcher of worlds, is she strong enough to mend a scorched landscape and bring the water home? Enter a raggedy witch trailing a storm of ashes: Magda, Crow's mother. She wants Mup to fulfill a promise. She wants Mup to help her. And woe betide any who stand in her way. Irish storyteller Celine Kiernan's breathtaking tale of family, loyalty, and risk caps a timeless trilogy brimming with drama and danger--and heartbreaking resonance to the struggles of today.
